just swapped a b16a2 into my 94 hatch. it has been burning oil and smokes pretty bad when vtec kicks in. any ideas what it could be?

 

I think you just answered your problem, you're burning oil. Oil smokes when it burns. Its probably oil leaking through the piston rings.

 

i wasnt sure ive heard people saying it could also be the valve seals wasnt sure what to try first

 

could be either, probably rings if burning at high rpm. Valve seals would burn all the time, or if the rings are really bad.

 

normally valve seals smoke at start up then eventually go away, but rings will do it all the time at certain rpm and above and if really wore all the time period. Id say rings though, my d16 would smoke around vtec because of the rpms, that and it had 200k on it haha

 

alright thanks
